Can anyone guide me how could I prepare this buffer? Should I first prepare 50mM potassium phosphate then 2 mM ethylenediaminetetraacetic acid (EDTA) .Then I should mix them and pH should adjusted by 50 mM sodium chloride (NaCl)?
The buffer prepared by dissolving 2.2727 g of KH2Po4 with 5.8002g of K2HPo4 in an amount of distilled water and after adjusting the pH to 7.5 then the volume was completed to a liter of distilled water. Jul 11, 2016
